CAT-D4b, D5: the windows' driver moves the old-name and the direct-write windows on start, delivered and manifest-reads-changed

The windows' logic was built but nothing woke it, so both windows stayed open for ever. The program now reads every
node through node_haves and the node-engine seat's manifest-reads at its start, on each delivered and on each
manifest-reads-changed, steps both windows, says their closing once on distribution.events and raises the seven-day
finding. A build module's have counts as publishing through the seats when it runs a build heard publishing (the
tools bundle records the fingerprint of each publish's proved caller), so a paused build agent running the same
build holds nothing open.
